Specification of Letters Patent.

Patented Apr. 113, 19215..

Application filed November 17, 1914. Serial No. 872599.

To aZZ whom it may concern:

Be it known that I, HARVEY P. BARNHART, a citizen of the United States,and resident of Portland, in the county of Multnomah and State ofOregon, have invented certain new and useful Improvements inWeed-Destroyers, of which the following is a specification.

My invention relates to means for destroying noxious plant life, and itis particularly adapted for use in destroying noxious plant lifefrequently found in lawns.

Herewfore appliances for digging and removing weeds have been employed,but such appliances have been found obj ectionable because of the laborinvolved in using them and the disfigurement of the lawn incidentthereto.

It is the object of my invention to provide a device for wounding theplant and depositing a destroying substance in the wound thus produced.

Another obyect of my invention is to construct the device in such amanner that the operator may use the device while standing erect.

Still another object of my invention is to so construct the device thatthe destroying substance may be deposited in asmall space therebypreventing other'plants from being damaged.

With these and other objects in view, my invention may be more readilyunderstood upon reference to the accompanying-drawing which forms a partof this specification.

In said drawingFigure 1 is a side elevation of the device; Fig. 2 is avertical section of the device showing the incising instrument in itsnormal position; Fig. 3 is a similar view showing the incisinginstrument in position to allow discharge of the destroying substance,and Fig. l is a fragmentary view of the incising instrument and partscarried thereby.

Referring to the drawing in detail in which like parts are representedby like numerals, 1 represents a fluid receptacle having a taperedportion 2 and a fluid intake 3. Positioned on the side of the receptacle1, are handles l. This receptacle may be constructed of any design butis preferably cylindrical as shown. Mounted within the. receptacle is anincising instrument 5 comprising a stem portion 6 having screw-threadedconnection at its top with a knob 7, and at ried by the stem 6.

its lower end with a knife mounting 8 car- Above the knife mounting 8 isa valve 9. The knob 7 is provided with a downwardly projecting extension10 providing a housing for a spring 11 which provides means forreturning the incising instrument to its normal position after it hasbeen actuated by the operator.

12 and 13 represent a pair of walls which provide means for positioningthe incising instrument in the receptacle. These walls also serve otherfunctions, the upper one, represented by the numeral 12 providing meansfor supporting the spring 11, and the lower one 13 providing a dischargeduct 14: for the delivery of the destroying substance.

The operation of the device is as follows: The operator places the knifeagainst the center of the plant and presses the knob 7. This splits thestalk of the plant and the upper part of the root. The receptacle 1 isthen raised by means of the handles 4:, whereby the destroying substanceis de livered through the duct 14 to the wound caused by the knife. Itwill be seen that the tapered end 2 of the device will prevent thedestroying substance from scattering and damaging other plants.

I claim l. A weed destroying device embodying a fluid receptacle, anincising instrument for cutting the weed associated with and adapted tohave vertical movement therein, a pair of guide walls provided in saidfluid receptacle, a spring for compelling the return movement of theincising instrument after it has been pressed downward and released, anda housing for said spring, one of said guide walls performing thecombined purpose of positioning the incising instrument and supportingthe said spring, and the other of said guide walls performing thecombined purpose of positioning the incising instrument and providing adischarge duct for the delivery of the fluid to the weed to bedestroyed, and means carried by the incising' instrument for controllingthe delivery of the fluid through said duct.

2. A weed destroyer embodying the fluid receptacle, an incisinginstrument for cutting the weed, associated with and adapted to havevertical movement therein, a discharge duct in said receptacle fordelivering the fluid to the weed to be destroyed, means carried by saidincising instrument for controlling the How of fluid through saiddisried by the incising instrument, to allow decharge duct, a knobprovided on the ineising livery of the fluid to the Weed.
